53 Claims.

,1 This invention relates tora supporting asing for collapsible tube, having extrudingmecha- .nism for the contents of said tube and haspareticular relation to an apparatus forldispensing .the plastic contents of tubessuch as tooth paste, shavingccream an'd'thelike.

Another object of the present invention is to ,provide adispenser of the character described embodying a frame adapted to be anchored to a wall or other 'fixed supportwith a rotatable spindle; or key, mountedzin the frame and shaped .to receive the closed rend of the tube, and, by rotation, to force the contents out of the neck of the tube, in combination with an enclosing housing which may be readily applied to or removed from the frame.

A further object of the present invention is to provide, in a dispenser of the character described, severing means for completely removing the ejected material and for closing the neck of the tube.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of the dispenser, partly broken away.

Figure 2 is a sectional View taken on the line 2-2 of Figure 1.

Figure 3 is a bottom end view; and

Figure 4 is a cross-sectional View taken on the line 4-4 of Figure 1.

Referring now more particularly to the drawings wherein like numerals of reference designate the same parts in each of the figures, the numeral I designates a bracket adapted to be secured to a fixed support such as a wall 2.

Fixed to and extending outwardly from the bracket there is a shank 3 and secured to the outer end of this shank there is an annular band 4, said bracket, shank and band constituting a frame.

The band 4 is provided with opposing bearings 5, 5 and rotatably mounted in these bearings there is a cylindrical shaped key 6 which is provided with a lengthwise slot 7 to receive the closed end of a tube 8 containing the material to be dispensed and which is formed of flexible material.

The other end of the tube 8 is formed with a tubular neck 9 which is externally threaded and a disc-like cap I0 may be screwed onto said neck, as best illustrated in Figure 2.

Eccentricall pivoted on thelower side of the caplll there is a disc-likeclosure plate Hwhich also *serves'as a cutter and whose free side is provided with apressure plate 12 whereby said disc-may be swung to open or "closed position.

One end of the key 6 isextended and fixed on said extended end "thereis a wing grip 13 "by means of which the 'key maybe turned.

There "is an inverted cup shaped housing I 4 whose upper end is permanently closed and whose lower end is open.

The upper side ofthe .cap I0 is reduced indiameter forming an external, annular, upwardly facing shoulder 15 and the lower end of the housing l4 may be fitted over said reduced portion of the cap closely and fitted against said shoulder.

This housing has two 1ongitudinal slots l6 and I! extendin from the open end thereof the required distance toward the closed end thereof, the former to receive the extended end of the key 6 and the latter to receive the shank 3 when the housing is fitted onto the frame, and it will be noted from an inspection of Figure 2 that the extended end of the key 6 is formed with an annular groove I8 which receives the side margins of the slot I6.

In use, with the frame secured to a support the closed end of the tube 8 may be fitted through the slot 1 and the cap I!) may then be screwed onto the neck 9 with the disc II in closed position. The housing I4 may then be fitted over the frame, as shown in Figures 1 and 2, with its free end fitted onto the cap 10. The disc-like closure ll may then be opened and the ke 6 then turned until the desired quantity of the contents of the tube have been forced out whereupon the closure Il may be swung to closed position.

As the tube 8 is emptied the housing M will move upwardly and when the tube is emptied and the housing has reached the limit of its upward movement the housing may be removed and the empty tube 8 detached and a full tube substitute for it in an obvious manner.

The drawings and description are illustrative merely while the broad principle of the invention will be defined by the appended claims.

What I claim is:

l. A dispenser comprising, a frame adapted to be secured to a stationary support and including a shank and an annular band secured to the shank, bearings in the band, a transverse key mounted to rotate in the bearings and having an extended end, said key having a transverse slot to receive the closed end'of a flexible tube which is adapted to roll about the key upon rotation of the key, a cap having a central opening to receive the neck of the tube, a housing adapted to be fitted snugly over the band of the frame and moveably carried by said frame, said housing having longitudinal slots leading from the open end thereof to receive the shank and the extended end of the key, respectively, said cap having a reduced upper end which fits snugly into the lower end of the housing.

2. A dispenser comprising, a frame adapted to be secured to a stationary support and including a shank and an annular band secured to the shank, bearings in the band, a transverse key mounted to rotate in the bearings and having an extended end, said key having a transverse slot to receive the closed end of a flexible tube which is adapted to roll about the key upon rotation of the key, a cap having a central opening to receive the neck of the tube, a housing adapted to be fitted snugly over the band of the frame and moveably carried by said frame, said housing having longitudinal slots leading from the open end thereof to receive the shank and the extended end of the key, respectively, and means on extended end, said key having an extended end and a transverse slot to receive the closed end of a flexible tube which is adapted to roll about the key upon rotation of the key, a cap having a central opening to receive the neck of the tube, a housing moveably fitted over the band and removeably supported on the cap, said housing having two longitudinal slots leading from the open end thereof to a point spaced from the closed end thereof, one of said slots accommodating said shank and the other of said slots accommodating said extended end of the key, and means on said extended end for rotating the key.
